9 Claims.

My invention relates to a punching device of the class for punching an air intake and a discharge opening in a can to permit pouring therefrom of its contents.

My invention has for its object to provide, in a manner as hereinafter set forth, a punching device enabling the punching selectively or simultaneously in a safe, easy and expeditious manner, of an air intake and discharge opening in a can whereby the necessity is obviated of ones being forced to resort to the expedient of hammering a sharp nail, knife or other sharp implement for the purpose, the use of such latter mentioned devices oftentime resulting in injury to the'hand due to the slipping of the nail, knife or implement used. 7

My invention has for its further object to provide, in a manner as hereinafter set forth, a punching device for selectively or simultaneously punching in a can an air intake and a discharge opening of like area or with the intake of less area than the discharge opening.

A further object of my invention is to provide, in a manner as hereinafter set forth, a punching device for the purpose set forth for simultaneously punching in a can an air intake and a discharge opening in parallel spaced relation'and for selectively positioning by separate means the intake and discharge openings at different distances apart.

Further objects of my invention are to provide, in a manner as hereinafter set forth, a punching device for the purpose referred to which is simple in its construction and arrangement, strong, durable, compact, thoroughly efiicient in its use, conveniently operated and inexpensive to manufacture.

With the foregoing and other objects in view, my invention consists of such parts and such combination of parts as are hereinafter more specifically described and as illustrated in the accompanying drawing, wherein is shown an embodiment of my invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawing:

Figure 1 is a side elevation of the device.

Figure 2 is a top plan view.

Figures 3 and 4 are sectional views respectively on lines 33 and 4-4, Figure 1,

Figure 5 is a top plan view of a can top punched by the device to provide it with an air intake and a discharge opening of like area, and

Figure 6 is a fragmentary view in top plan of a can top punched by the .device to provide it with a discharge opening of enlarged area.

The device includes a carrier I for two pairs of oppositely disposed punches tobe referred to. The carrier I is of bar like form and it'consists of central rectangular part 8, a pair of rectangular hollow parts 9, I open at their tops and bottoms and constituting housings, a pair of oblong parts I I, I2 and a pair of oppositely disposed tapered end parts I3, I4.

The housings formed by the parts 9, III are of like form and each includes an inner end wall I5, an outer end wall I6 and a pair of spaced parallel side walls I'I, I8. The walls I5, I6, I1 and. I8 of the housings coact to provide rectangular chambers I9, 20 open at their upper and lower ends. The ends of, the central part 8 merge into and at the vertical medians of the end walls I of the housings. The inner sides of the parts I I and I2 merge with and at the vertical medians of the outer end walls I6 of the housings. The outer sides of the parts II and I2 merge into the inner ends of the parts I3, I4 respectively. The side walls of the housings are outset with respect to the parts 8, II and I2 of the carrier 1. Secured upon the parts I3, I4 are oppositely extending handle members 2|, 22 respectively.

Arranged in and disposed lengthwise of the chamber I9 is an S-shaped body 23 common to a pair of oppositely extending punches 24, 25 of like form. Each punch is of rectangular contour in transverse cross section and is formed of a shank 26 terminating in a puncher or piercer 2! of tapered contour. The shanks and punchers or piercers of the punches 24, 25 are of like form and size. The body 23 includes a pair of oppositely disposed U-shaped bends 28, 29. The bend 28 opens in a direction towards the top and the bend 29 opens in a direction towards the bottom of chamber I9. The outer edge of bend 28 is flush with the lower edges and the outer edge of bend 29 is flush with the upper edges of the side walls of chamber 9. The outer end of body 23 is at the top edges and the inner end of the body 23 is at the bottom edges of the side walls of chamber I9. The shank 26 of punch 24 merges into the outer end of body 23. The shank 26 of punch merges into the inner end of body 23. Extending transversely of the part 9 of carrier I is a pair of spaced parallel rivets 30, 3| having their ends upset and bearing against the outer faces of the side walls of chamber I9. The rivets 30, 3I bear against the inner edges of the bends 2B, 29 respectively. The rivets function 1 9 anchor body 23 to part 9 and to prevent longitudinal and vertical shifting of body 23 with respect to chamber I9.v

Arranged within and disposed lengthwise of the chamber is an S-shaped body 32 common to a pair of oppositely extending punches 33, 34 provided with shanks 35, 35 of rectangular cross section. Integral with the shank and forming a part of punch 33, 35 is a tapered puncher or piercer 3'! of rectangular cross section and of the same size as the puncher or piercer 2'! of the punch 24. The shank 36, at its outer end, is headed, as at 33, and has mounted thereon between head 33 and the top edges of the side walls of the chamber 23, as well as bearing against said edges and head, a hollow puncher or piercer member 39 of substantially right angled contour in side elevation forming a part of punch 34. The vertical leg 49 of member 39 extends beyond the outer end of the inclined leg 4| of member 39. The leg 43 has a cutting edge 42. The leg 4| has side cutting edges 43. The member 39 constitutes a puncher or piercer which is of rectangular contour in plan and is of greater length, breadth and width than that of the puncher 31.

The puncher or piercer of the punch 24 is arranged in parallel relation to the puncher or piercer of the punch 33. The puncher or piercer of punch is arranged in parallel spaced relation to the puncher or piercer of the punch 34, but the distance between the puncher or piercer of the punch 25 and the puncher or piercer 39 is greater than that between the puncher and piercer of the punch and the puncher or piercer 31.

The body 32 includes a pair of oppositely disposed U-shaped bends 44, 45. The bend 44 opens in a direction towards the top and the bend 45 opens in a direction towards the bottom of chamber 20. The outer edge of bend 44 is flush with the upper edges and the outer edge of bend 45 is flush with the bottom edges of the side walls of chamber 20. The inner end of body 32 is at the bottom edges and the outer end of body 32 is at the top edges of the side walls of chamber 29. The shank 35 merges into the inner end of body 32. The shank 35 merges into the outer end of body 32. Extending transversely of portion IQ of carrier 1. is a pair of spaced parallel rivets 46, 41 having their ends upset and bearing against the outer faces of the side walls of chamber 23. The rivets 46, 41 bear against the inner edges of the bends 44, 45 respectively. The rivets 46, 41 function to anchor body 32 to part 9 of carrier I and to prevent longitudinal and vertical shifting of body 32 with respect to chamber 20.

The punchers or piercers 21, 35 function to form the top 48 of the can with the rectangular openings indicated at 49. The function of puncher or piercer 39 is to form the top 50 of the can with a rectangular opening 5i of greater area than the openings 49. When the puncher or piercer of the punch 25 is used in connection with the puncher or piercer of the punch 33, and when pressure is applied upon the device, the two punchers or piercers will provide simultaneously in the can top, a pair of diametrically opposed openings, of like form. One will constitute an air intake and the other an outlet or discharge opening for the contents of the can. When the puncher or piercer of the punch 24 is used in connection with the puncher or piercer 39, and when pressure is applied upon the device, these two punchers or piercers will provide simultaneously in the can, a pair of diametrically opposed rectangular openings of different area, the smaller of which will constitute an air intake and the larger of which will form an enlarged outlet or discharge opening, thus enabling the contents of the can to be freely poured therefrom.

When the punches 24, 34 are used, the openings 49, 5i respectively provided thereby will be a greater distance apart than the openings 49 provided by the use of the punches 25, 33. The openings 49, 5 l are of rectangular shape but with the opening 5! of a size appreciably larger than openings 45.

It is to be understood that the puncher or piercer 31 of the punch 33 may be of the same construction as that of the puncher or piercer 39 of the punch 34.

That portion of one of the lengthwise edges of the carrier between the handle members 2! and 22 constitutes a stop for arresting the punching action of the punches 25, 34 and that portion of the other lengthwise edge of the carrier between the handle members 2| and 22 constitutes a stop for the punching action of the punches 25, 33.

The S-shaped bodies 23 and 32 constitute spaced coupling means for connecting the punches to and in extended relation with respect to the lengthwise edges of the carrier.

The material of the cantop which is freed by the puncher or piercer 39 is extended into the can by the action of the puncher or piercer. This prevents any possibility ofinjury to the hands by reason of handling of the can and contact with rough edges which might otherwise be formed. At the same time, the appearance of the can top is not rendered unsightly but is The said freed portion will permit free and ready pouring of the contents from the can.
